Teflon Bellow Seal WM152

Teflon Bellow Seal WM152 is designed to handle highly corrosive chemicals, such as concentrated acids, caustic, strong oxidizing and reducing agents, and chemically active organic components. All elastomers have both an upper and lower temperature limit that prevents them from sealing many hot resins, polymers, and cryogenic applications. Teflon Bellow Seal WM152 is outside mounted with the simple installation procedure and hence cost-effective for corrosive media sealing.
